Development, characterization and transferability of microsatellite markers for the plant genus Phlox (Polemoniaceae)

In order to study diversification and microevolution in Phlox, we developed nine polymorphic microsatellite loci. In 20 individuals of Phlox pilosa from a single population, the average number of alleles per locus was 10.0 +/- 5.1, and average observed and expected heterozygosities were 0.611 +/- 0.234 and 0.769 +/- 0.170, respectively. Most of these markers amplified successfully in 11 additional species of Phlox, representing a broad diversity of the genus, and some also amplified in more distantly related members of the Polemoniaceae. These microsatellite markers will be valuable for investigation of evolutionary processes in this important study system.
